<p>A flow meter is provided using a fluid responsive solid member (7) which is introduced into a flow chamber (6) defined in a vertically standing tubular housing (1) and which, with the flowing fluid (F) supplied through an.inlet (2, 3) at the lower end of the housing and discharged through an outlet (4, 5) at the upper end of the housing, is propelled to a level as a function of the volume rate of flow of the fluid (F) within the chamber (6). The solid member (7) is composed at least in part of an electromagnetically susceptible material and an electrically conductive winding (8) is disposed in an electromagnetically inductive relationship with that member (7) to present a reactance which varies as a function of the propelled position of the member (7) in the flow chamber (6).</p> |
